View 4 RepliesI was asked to create a program that inserts records into one parent table and multiple child tables. My question is, how do I know what the PK is for the parent table, so that I may add it as a FK in the child? The PK for the parent is an auto number. As I stated in my title, I'm using VB.net, mySQL, through an ODBC connection. I have to do this through the code and cannot use stored procedures.
my transaction looks like this:
Dim cmdText As String = "INSERT INTO candidate(first_name, last_name, phone1, phone2, email1, city, " _
& " state, country, zip,primary_contact_id ) VALUES (?,?, ?, ?,?,?, ?,?,?,?)"

I am trying to search through records of my database in a VB form and I don't have any errors or warnings but it doesn't work.
Here is the code and a screenshot:
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
Dim search As String
search = boxSearch.Text = txtSearch.Text & "'"
Dim foundRows() As DataRow
foundRows = taxDS.Tables("Orders").Select(search, boxSearch.Text)
End Sub
txtSearch.DataBindings.Add("text", taxBS, boxSearch.Text)
boxSearch.DataBindings.Add("text", taxBS, boxSearch.Text)
I'm loading my listview with records from a mySQL Table, which works great. But I'm having issues when I try to add records to another listview according the selected row in the first listview.
vb.net
Dim mysqlDataComm As New MySqlCommand("SELECT jan, feb, mrt, apr, mei, jun, jul, aug, sep, okt, nov, dec FROM data_table WHERE datum ='" & frm_main.Listview1.SelectedItems(0).SubItems(1).Text & "'", mysqlConn)Dim mysqlReader As MySqlDataReaderTrymysqlConn.Open() With frm_main.lstv_data.Items.Clear() mysqlReader = mysqlDataComm.ExecuteReader While mysqlReader.ReadDim lvi2 As New
[code]....
It works until ".Items.Clear()"... after that nothing happens and I really don't know what I'm doing wrong. No error, whatever.
I'm trying to make a program that takes my old records from Access and moves them to MySQL. Its supposed to take records from 3 different tables in Access to 3 different tables in MySQL. The first table is "Orders" and it sorts the ones to pull to the dataset, taxDS, by "Where Status = 'Waiting Payment' OR 'Cancelled'". Then the second table pulls its info(this is where i'm having trouble) by the "Control_Number" in the "Orders" table, so basically if the control number isnt already in the dataset its not going to pull the data into the new table "FNF Taxes".

How can I design a datagrid that displays records and when one record is double-clicked, you can edit that record or when the datagrid record is double-clicked you can view the past history of that particular record in detail?
If you can view the "chart of accounts" in QuickBooks, then you will understand what I mean.

I have a populated datagrid that has some fields that are needed for calculation in my app. In the dataset they are set to Allow DBNull False because I can't have a DBNull in my calculation for obvious reasons. I have found answers to incorrect data entry and blank fields in these critical fields (see code block below), but they only work if some data is entered somewhere in the new record, even if I populate the field with default values other than <DBNull> on adding a new row. If a user doesn't add any information and just tabs through a new record/row or cursors down the app blows up. If they cursor up without entering any data, the blank field procedure for these protected fields engages fine.

there is a datagrid in a form. i need, when a user hit tab in a particular cell, another form holding a list of records needed to be displayed, allowing the user to select one or more than one records, and after selection all those records are needed to get populated in the first datagrid.
View 4 RepliesI am developing a Windows application in Visual Studio 2005, V2.0 using VB.NET. I am coding part of an Emergency Response Information System. On my form, I have two combo boxes (cboBaseStationID and cboPriority). I am trying to populate the datagrid with records from my database based on what is selected in both comboboxes.
For the first combobox, the user selects a name so the datagrid must only show records with that name. For the second combobox, this is a little more complicated. There are four emergency priorities in the combobox that the user can choose - 1, 2, 3, 4. In the database, there are different response teams (to be dispatched to these emergencies) and each response team has a grade of either 1, 2 or 3. [Code]

I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.
